Senator Henry M. Jackson spent a week in Antarctica in October 1959 as part of Operation Deep Freeze 60, which was a support program for U.S. scientific research efforts. The program was responsible for bringing in and dropping supplies to Byrd Station, Hallett Station, McMurdo Sound and South Pole Station. He visited McMurdo Sound, New Zealand's Scott Base, South Pole Station and other points between stations.

Jackson flew with the MATS C-124 Globemaster crew during the crew's successful air-drop of a nine-ton Caterpillar tractor to South Pole Station.
